Ripening and extruding device with series screw rods for making rice noodles and method thereof

Abstract

A series screw rod ripening and extruding device for rice noodles production, and the device comprises a first-level screw rod self-ripening extruding machine and a second-level screw rod thread-extruding machine The invention also relates to a manufacturing method of rice noodles utilizing the series screw rod ripening extruder. The device of the present invention can be used to manufacture rice noodles, during which process ripening extrusion strength and shearing force increased, and the rich noodles made by this device contains plenty of gel. The production capacity is higher and it is energy-saving remarkably, the production efficiency is improved and furthermore, the device can be maintained conveniently.

1 . A ripening and extruding device with series screw rods for rice noodles production, characterized that:
 the device comprises a first-level screw rod self-ripening extruding machine and a second-level screw rod thread-extruding machine,   the first-level screw rod self-ripening extruding machine comprises a first-level barrel, which comprises a first-level feeding inlet at one end and a first-level discharging outlet at the other end, the first-level barrel is provided with a self-ripening screw rod inside, which is coupled to a driving device I at one end;   the second-level screw rod thread-extruding machine comprises a second-level barrel, which comprises a second-level feeding inlet at one end and a second-level discharging outlet at the other end, the second-level barrel is provided with a thread-extruding screw rod inside, which is coupled to a driving device II,   the first-level discharging outlet is coupled to the second-level feeding inlet.   
     
     
         2 . The ripening and extruding device with series screw rods of  claim 1 , characterized that, the driving device I comprises a motor I and a reduction gearbox I, and the said motor I is coupled to the reduction gear box I, which is coupled to one end of the self-ripening screw rod. 
     
     
         3 . The ripening and extruding device with series screw rods of  claim 1 , characterized that, the driving device II comprises a motor II and a reduction gearbox II, and the said motor II is coupled to the reduction gear box II, which is coupled to one end of the thread-extruding screw rod. 
     
     
         4 . The ripening and extruding device with series screw rods of  claim 1 , characterized that, the said self-ripening screw rod and the thread-extruding screw rod may be single-screw rods or double-screw rods. 
     
     
         5 . The ripening and extruding device with series screw rods of  claim 1 , characterized that, the thread on the said self-ripening screw rod and the thread-extruding screw rod may be equal or unequal in length. 
     
     
         6 . The ripening and extruding device with series screw rods of  claim 1 , characterized that, the first-level discharging outlet and the second-level feeding inlet are both funnel-shaped openings. 
     
     
         7 . A method of using the ripening and extruding device with series screw rods of  claim 1  for rice noodles production, comprises ripening stage and thread-extruding stage,
 during the said ripening stage, the operating temperature of the self-ripening screw rod in the first-level screw rod self-ripening extruding machine is in the range of 120-140 Celsius degrees, the revolving speed of the self-ripening screw rod is 500-800 rpm, and the time required for the rice flour to be ripen and extruded from the first-level barrel is 2-12 seconds, and 
 during the thread-extruding stage, the operating temperature of the thread-extruding screw rod in the second-level screw rod thread-extruding machine is in the range of 60-90 Celsius degrees, the revolving speed of the thread-extruding screw rod is 30-150 rpm, and the time required for the rice flour to be extruded in form of threads out the second-level barrel is 2-12 seconds.
